Abstract

The Dynamic Host Configuration Protocol (DHCP) provides a framework
for passing configuration information to hosts on a TCP/IP network.
Configuration parameters and other control information are carried in
tagged data items that are stored in the 'options' field of the DHCP
message. The data items themselves are also called "options."

New DHCP options may be defined after the publication of the DHCP
specification to accommodate requirements for conveyance of new
configuration parameters. This document describes the procedure for
defining new DHCP options.

1. Introduction

The Dynamic Host Configuration Protocol (DHCP) [1] provides a
framework for passing configuration information to hosts on a TCP/IP
network. Configuration parameters and other control information are
carried in tagged data items that are stored in the 'options' field
of the DHCP message. The data items themselves are also called
"options." [2]

This document describes the procedure for defining new DHCP options.
The procedure will guarantee that:

* allocation of new option numbers is coordinated from a single
authority,
* new options are reviewed for technical correctness and
appropriateness, and
* documentation for new options is complete and published.

RFC 2489 Defining New DCHP Options January 1999

As indicated in "Guidelines for Writing an IANA Considerations
Section in RFCs" (see references), IANA acts as a central authority
for assignment of numbers such as DHCP option codes. The new
procedure outlined in this document will provide guidance to IANA in
the assignment of new option codes.
